HAIR WAVIN'G AND CURLING DEVICE.

To all whom it may concern:

Be it known that we, HANNAH J ACOBS and HARRY JAooBs, citizens of the United States, and residents of New York city, in the county of Kings and State of New York, have invented certain vnew and useful Improve ments in Hair Waving and Curling Devices, of which the following is a specification.

This invention relates to an improved hair waving or curling apparatus which is adapted to engage about. a winding stem upon which the hair has been wound or curled and is in the nature of an improvement over a similar device for which our application was filed on April 13, 1916; which application bears Serial Number 90,888 and was allowed on June 7th, 1916.

The object of this invention is to provide a device of the character described which will accomplish the same purpose as that set forth in our said former application but which will be simpler in construction, more readily applied to use and be more economical in cost of manufacture.

We attain these objects by the device illustrated in the accompanying drawings in which Figure 1 is a side e ovation of the completed device, Fig. 2 is an end view of same; Fig. 3 is a longitudinal section through the device; Fig. 4 shows a front view of a cushion the function of which will be hereinafter explained; Fig. 5 is a section through the outer casing showing the internal members and cap removed and Fig. 6 is a view of a portion of the device which will be hereinafter termed the drying chamber and which shows its members detached.

Referring to the parts 1 is a casing having a threaded portion 2 along the outer periphery of its open end 3, the opposite inner end, 4 of the casing 1 is formed with an inwardly projecting portion, 5 which is adapted to engage a resilient washer or cushion 6, one side of which is formed with a concave surface 7 adapted to receive the base of a vacuum insulating member 8, the said cushion 6 is also formed with a cut out portion 9 providing a space for locating the sealing stem 10 of the said vacuum insulating member 8 affording thereby a protection for the said stem 10 against breakage from undue pressure when the parts are secured together. A central perforation 11 permits the said cushion 6 to engage over the inwardly projecting portion 5 of the said casing 1.

A heat insulating member 8 preferably a Specification of Letters Batent.

insulating member 8 by an insulating plate 13.

The said insulating plate 13 is a part of a cap 14 threaded at its inner periphery 15 and adapted to engage with the threads 2 upon the casing 1. The said cap 14: is rig idly attached to the said insulating plate 13 at 16 and is formed with a circular knurled portion 17 provided to facilitate the turning of said cap 14.

The said insulating plate 13 has a central threaded perforation 18 in which the threaded end 19 of a tube or drying chamber 20 is'adapted to engage.

The said tube or drying chamber 20 is preferably made of copper and provided with a flange or shoulder 21 which is adapted to engage the washer 12 to hold same securely against the insulating plate 13. An annular flange or ledge 22 is formed at the outer edge of the perforation 18 in insulating plate 13 to provide a stop for the edge 23 of the drying chamber 20.

The said cap 1 1' and its attached insulating plate 13, the washer 12 and the drying chamber 20 are secured together as a unit of the device and engage, by means of the threaded portions 15 and 2, upon and with in the casing 1 and act to hold in place the aforesaid insulating member 8 as indicated in Fig. 3. The parts are tightly screwed together so that sufficient pressure is brought upon the washer 12 by the edge of the insulating member 8 to make'a water tight joint between said washer and insulating member.

Grooves 24: are formed upon the said insulating plate 13 and are adaptedto hold a sliding plate 25 which is made of any suitable non-heat conducting material. Supporting eyes 26 are provided upon the easing 1 as shown.

In the application of this device to use, the hair is first wound, in the usual Way upon a stem and fastened thereon. The stem, with the hair upon it, is then inserted in the drying chamber 20; the said drying chamber 20 and its parts having first been attached to and within the casing 1. The aforesaid insulating member 8 being also located within the casing 1 as shown in Fig,

3. Hot liquid, preferably water, is contained within the insulating member 8, between the inner wall of same and the wall of the drying chamber 20 and constitutes the medium for supplying heat to the drying chamber 20; the insulating member 8 wish to be understood as limiting ourselves to the particular construction shown;

What we do wish to secure by Letters Patent is In a hair waving and curling apparatus, a heat-insulating member adapted to contain a liquid heating element, an outer jacket inclosing said liquid containing member, a drying member concentrically fastened to the said outer jacket and extending concentrically within the said liquid containing member, a heat-insulating head or block securely fastened to the said drying member and detachably connected to the said outer jacket, a resilient washer or gasket held upon the said head and interposed between it and edge of the liquid containing member, a resilient seat located within the said outer jacket and adapted to afford a base for the said liquid containing member and a means for closing the opening in said head.
